HEATING AND VENTIIJATING UNIT.

Application filed August 27, 1921. Seriall No. 496,082.

To all whom t may concern:

Be it known that I, CnARENcFl` C. SHIPP, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and useful Improvements in Heating and Ventilating Units, of which the following is a specification.

This invention relates to AVentilating apparatus for steam heated houses wherein radiators either Wholly or partially encased draw their supply of air from Without the building through boxes located in the Walls of the rooms.

I have previously used a Wall-box and a tubular i conduit extending horizontally therefrom to the base of the ventilator, but

thevvooden strip required in the conduit for nailing the assembledparts tofhas restricted the cross sectional area of the conduit, thereby reducing its airisupplying capacity, and the air, by being delivered to the radiator casings in straight lines, has no contacting surface to beat against and break its force and to preventthe carrying in of rain, snow and dust.

The object of this invention is to provide ample room for a ventilator box and for a tubular conduit of` unrestricted capacity; anda further object is to deflect the cur- 'rent of air from a straight line and to contact it with a surface at such an angle to the initial flow as to retard the elements carried in byit, anddeliver the air into the radiator casing in a more quiet and neutral condition than heretofore. i

l accomplish the above, and other objects Which will hereinafter appear, by the mechanism illustrated in the accompanying drawing, in which Fig` 1 is a vertical section of the Wall and oor of a room With my invention in perspective and vertical section assembled therein operatively With an incased radiator. This ligure shows the damper which controls'the supply of air, and its operating mechanism, inclosed position of the damper. Fig. 2 is a detail in vertical section of the vmechanism shown in Fig. l`

' with the damper in full open position, and

Fig. 3 is a section on the line 3-3 of Fig. 2 showing the metal fold on which the ends of the damper rest when closed.

Like characters of reference indicate like parts in the severalviev/s of the drawing.

The radiator sections l may be and are of any usual and suitable construction, tio which steam is supplied in the usual manner for the radiation of heat to heat the room in which the sections are placed. The radiator sections are Wholly or partially enclosed by a sheet metal casing 5, usually supported upon a cast-iron base 6. The above parts' are assembled near a Wall T ot a building of which the room to be heated is a part. For sanitary reasons it is desirable to create a circulation of air in the heated room, provide the latter With a ventilator (not shown) at the top for the discharge to atmosphere of foul air, and to draw in air from the outside of the building to take the place of the air discharged thereby `producing a circulation in which pure air is substituted for impure air. rl`his is accomplished by connecting a suitable opening in base 6, o-n the side neXt to the adjacent wall of the room, with a vertical air-chute 8, by means of a suitable sleeve, here shown as in tivo telescoping sections 9 and 10, to allow for any adjustment in distance between the radiator casing and chute, caused by variations in the thickness of Wall 7 or the distance Which the radiator is set from said Wall. A Wooden header 11 is placed above the telescoping sleeve, in the Wall, to`be used as a nailing-strip for the attachment of the sleeve and chute. The vertical extension of the sleeve 8 and its cross sectional area will depend upon the requirements and condition of the installation, but it will be sufliciently long to change the flow of air from direct to indirect liciv and to provide a Wall 12 as a baille plate for the air to beat against for the removal of snow and rain and the dislodgement of dust particles. llhe chute 8 connects with the bottom of a WallboX 13, the outer niember of Which ispreferably made out of cast iron with the usual storm louvers 14. It Will also have the usual Wire insect screen 15. and therdischarge through the Wall-box into the vertical chute 8 ivill be regulated and controlled by a damper 16, having' one edge hinged at 17 to the Wall 12 of the chute S, and extending thence downwardly and obliquely across the chute 8, with a bearing at its lower opposite edge upon the bottom of the Wall-benin the manner shown. The ends of the chute S, like the sides of said chute, are preferably formed out of sheet metal and will have flanges 19 bent therefrom in the manner shown inFi-g. Sand inturned `ololiquely as rests for the ends 4of the damper 16 when the damper is in its closed position.

The damper 16 lhas a pair of under-side ears to which the upper end of `an operating bar 20 is hinged. The lower end of the bar 20 is hinged to an arm of a T-shaped lever 21, the stem of which is hinged to ears 30 attached to the bottom of plate 12. A footbar 22 laasone end hinged to the opposite arm of "the T -shaped lever from that to which thefibar 20 is hinged, and the opposite .end of the toot-bar 22 is extended .through a suitable slot ,23 in .the .iront orboX-'base 6, and is sufficiently Vcontinued to atlord suitable lengthfo-r :manipulationby the 'loot of a person desiring to change` @the position `ot lthe' damper. The end otfoot-bar 22 projecting Ein front ,oli-base plate 6 is provided With aiplurality ot' ynotches Y241 in its upper edge zt'or engagement with. the plate '6 in the ,inanner shown iin-Fig. 2 to hold a given adjustment oit the ,damper 1,6. The :foot-bar 22 will preferably ybe'initwo lapped parts, one of which fis longitudinally slotted and the other provided with 'bolts through said slot, Where- ;by the length of the foot-bar may be changed totitthelocation of the box-base 6 in its :distance from the chute 8. Connection lbetweenthe opening in the rear of lbase `6 and theVtWo-part sleeve comprising members 9 :and 10 is by a `sleeve 25 having a vertical Wall-flange 2G. 'The .position of the radiator casi-ng is retained Vby nailing a Wooden quarter-round 27 to the floor of the room 2S against the rearboX-base 6.

ln'the operation of my invention, thead- .j-ustable sleeve members 9 and 10 and adjustable foot-bar 22 provide `.inea-ns for setting the parts to lit the location Vof the chute 8 in the 1Wall-,and the dista-nce ofthe radiator 4 from the Wall. The carrying of the chute 8 upverticaflly to a considerable distance above-the-'sleeve*connection with the radiator-casing linales a bend in the air-inlet which prevents-ia `direct ydraft or current of air i from `the outside to the radiator-casing, eliminatessnow and rain and :dust to Aa large extent, but, moreover, it provides `for -con- .necting with the vbottom of the radiator-box,

' *instead of the Iend of` the .-boX, and thereby allows for the use of a much larger chute in cross-.sectional arca than would be permitted otherwise; .and .by placing the damper :obliquely across the chute Tin the `box ample kroom for the swing of the damper is obtained fand a substantial' bearfi-ng onV the bottom of the box is provided for the damper When closed.

In the opening and closing of the damper the foot-.bar22 is readily adjusted by apressure "of the operatoi'"s foot `and ya given adjustment is held 4by the engagement of a side of one of the notches with the Wall ot the .base i6, ,the Weight oft' the dai-hiper.serving to hold the` adjustment until-'the foot-bar is released by a downward pressure on its outer end which lowersthe upper edge of the bar and its notch outI of contact with A pin si in ai@ foot-bai# 22 hoids the bar `from movingendivise too far through the box-base 6.

The damperv 16 in openposition. plie-vents .the format-ion of `a dead lair pochetin-.the corner above it kand starts `the air y.downivardlyinto the chute 8.

While I have described and .shown the 4best form `of my invention lnow'ltnownto ine,it is y obvious that changes .may be made :inathe position of the wall-box and the construction Vand operation ofthe damper,` and .other matterseand I .therefore do not .desireto be' limited nnduly, or any :more than is required by the appended claims, and what l claim is 1.
